Steven, your switch is normal and correct for your model, provided that it's staying in the "up" position and not "down". As Stacey says, there are different switches with different operation for various models.
On the first models with electric flaps up to and including the 1967 G, the flap switch returns to center when released from either direction. In those models, the flap motor keeps turning even when either travel extreme is reached -- damage is prevented by a clutch. In 1968 a limit switch was added at the retract extreme so the motor would stop when the upper limit is reached. The flap switch on those models works as Stacey describes. Some time after that, the set-and-forget flap system was implemented, where you have several flap settings you can choose and the flaps will go to the selected position and stop.
You should use the switch type appropriate for your model plane.
